ABSTRACT:
A powered conveyor roller having a frictional coupling inside the roller drivingly connecting the roller to a drive shaft extending actually through the roller. The coupling includes a flat spring wrapped around the shaft to form a frictional engagement with a pair of split bushings disposed on the shaft and inside the spring, the opposite end of the spring being connected to the roller in such a manner that the roller is driven by the shaft up to a predetermined load on the roller but the shaft and roller rotate with respect to one another when the load exceeds a predetermined, adjusted level.
